     1 Release notes for lxdream 0.9.1 "Turtle"
     2 ===================================================
     4 Lxdream 0.9.1 is mostly a performance release (core emulation is a good
     5 33-50% faster, although rendering performance is still bad), with a few new
     6 features like VMU and LIRC support. As for 0.9, the majority of software can
     7 be expected to "just work" with minimal problems.
     9 Nevertheless this should still be considered an alpha release, with many 
    10 unimplemented features remaining. You're unlikely to see 'perfect' emulation,
    11 and we're nowhere near being bug-compatible (in other words, don't expect your
    12 code to work on the real hardware just because it runs correctly in lxdream).
    14 Changes since 0.9
    15 -----------------
    16 * Lots of core performance improvements, especially with the MMU turned on
    17 * VMU support (memory card only)
    18 * GDB remote debugging support
    19 * Quick-save states
    20 * LIRC driver
    21 * Now uses the ~/.lxdream directory (by default) to store runtime data
    22 * Audio + input drivers are now built as plugins
    23 * OSX: fullscreen support, minor UI improvements
    25 Known issues
    26 ------------
    27 The following are known problems in 0.9 that will be fixed in the next major
    28 release - in other words, you don't need to report them - we already know :)
    30 * Graphic artifacts related to translucent triangle intersections, sorting errors 
    31   and/of lack of depth precision.
    33 * Rendering performance ranges from barely acceptable to abominable.
    35 * The SH4 emulation is not cycle accurate, and (by default) usually runs
    36   slower than the real one. This cause some programs to have timing problems
    37   or to break completely. In some cases this can be worked around by
    38   adjusting the CPU scaling factor (-m command line option)
    40 * Audio quality generally ranges from poor to horrible, interrupted by the
    41   occasional bit of fair-to-middling sound. 
    43 System requirements
    44 -------------------
    45 Linux:
    46    GTK 2.6+
    47    Current (2008 or later) ATI or NVidia binary OpenGL drivers 
    48       - If anyone wants to fix the free drivers, lxdream specifically
    49         requires a working implementation of either the EXT_framebuffer_object
    50         or GLX_SGIX_pbuffer extensions. 
    52 OS X:
    53    System 10.4 or later
    55 GCC, Make, etc.
    57 Building
    58 --------
    59 From the base directory
    60 ~$ ./configure
    61 ~$ make
    62 ~$ make install            (optional, GTK only)
    64 Enjoy!
